special preparation, and-will not deteriorate under ordinary conditions. The cleaning and polishing compound. comprises a mixture of quicklime, kerosene,

stearic acid and tallow, and the following 1 preparations of these ingredients have been found to give excellent results.

To produce approximately 160 pounds of the compound I obtain approximately 80 pounds of quicklime. This qnicklime is ordinarily lumpy or coarse and unslacked. I grind it'to a powder and run it through a fine sieve so as to remove all grit with the result that I have a 'fine smooth quicklime powden' Next approximately 40 pounds of kerosene- 25 is placed in a suitable mixing machine which I may be driven by power or manually operated.

Then about 20 pounds of tallow is heated to the melting point, and together with, about 3020 pounds of stearic acid is added to the kerosene within the mixing machine. These three ingredients, melted tallow, stearic acid,

' and kerosene are thoroughly mixed, and then approximately 20 pounds of the qui'cklime powder, previously prepared, is added to the mixture. After thisquicklime has thoroughly commingled with the mixture, the remainmg quick lime powder is added and the whole batch thoroughly agitated so as to insure a thorough distribution of all-of the ingredients. l.

The mixture within the machine is semiliquid and is run oif'into suitable containers, in which it somewhat solidifies and takes the form of a paste.

The paste-like compound has for its prin- Application lile i September 23, 1926. Serial No. 137,386.

and yet be harmless to the hands of a user.

A rag maybe passed over the compound to obtain 'sulficient compound for the application to the surface to be cleaned and pol-- ished, and in practice I find that a very small quantity of the compound removes all stains, dirt and foreign matter from the surface to be cleaned and polished.

to obtain action o'n'the surface, and then a clean rag may be used for removing any of the compound on the surface and polishing the same.

I attach considerable importance to the quickliine ingredient which is approximately 62 percent calcium oxide, and 38 percent magnesium oxide, the quicklnne being comparatively high in magnesia, and since the same is in a very fine powdered condition,

with all grit removed, there is nothing whatsoever in my cleaner or polisher that will. scratch, mar or otherwise injure a highly finished metallic surface, for instance, the metallic trimmings or fixtures of an automobile for which my compound has been especially provided'for removing water stains and the like.

Obviously the proportions of tlieabove 111- gredients may be varied, also the manner of mixing the compound.

What I claim is A metal cleaning and polishing compound consisting of the following ingredients in approximately the following proportions by weight: parts of quickliine high in magnesia, 40 parts of kerosene,'20 parts. of stearic acid and 20 parts of tallow. In testimony whereof I aflix my signature.
